Hello everyone! Does anyone know how to override the cooling fan, so that it runs at 100%? My fan sounds like its not spinning as fast anymore, compared to few months ago. Is there an override like on the corvettes? I don't have star diagnostic, so i can't use that.

Oh and my coolant temp is constantly getting to 100C sometimes passing that, still the fan barely runs. If I turn the A/C on, the fan turns on, not full speed. Shouldn't the car try to get the temperature down to 85 C? Ambient temp is 70F.

I figured out how to test the fan. You start the engine and on the climate control settings. Push and hold the "REST" and Recirculate buttons for 8 seconds. You will see a menu pop up. Use the left temperature selector and select number 12 and use the right side to change the % to EIS. Or 100%. You can select the percentage of which you want.

As for my fan, its working and it does kick into 100% mode. Not sure why it doesn't go to 100% when the engine temp is at 105C.

The cooling fan turns on at 95 C and stays on until 90C usually the speed is 50%. When driving in the cold, the thermostat will keep the temperature at 85C
